Seats, steering wheels and pedals define your connection with the car

A seat with good side bolstering can hold your body in place, so you steer with your hands instead of holding on to the wheel. Under seats and seat covers you will find, for example, Rugged Ridge seat covers for the Jeep Wrangler TJ and JK, and among steering wheels, shift knobs and other equipment in the category you will find brands such as SPARCO and NRG. Under pedals and pedal pads there are also complete pedal assemblies, for example from Wilwood, with an adjustable balance bar, in floor-mounted or reverse-mounted versions and with pedal ratios from 5:1 to 6.25:1. The pedal ratio affects how much foot force and pedal travel is required, while the balance bar distributes the force between two master cylinders so the brake bias can be adjusted.

How to choose interior parts

Fitment: mats and covers are typically made for specific model years, body styles and seat rows. Compare the product name with your car.

Purpose: a street car, work vehicle and track project place different demands on grip, durability and weight.

Installation: seats and steering wheels often require brackets, rails or hubs that fit the car, and pedal assemblies must match the master cylinders and the space in the footwell.

Approval: whether seats, steering wheels, pedals and mirrors are road legal depends on the product and the car. Check the approval for the specific part number before installation.

Mats, sound deadening and keeping the car organised

Floor mats and cargo mats protect the carpets from water, salt and dirt. Examples include 3D MAXpider Kagu mats for cars such as the Subaru Impreza WRX STI and Infiniti G37, as well as Husky Liners X-Act Contour mats for the Kia Sportage that follow the shape of the floor. Mats must be secured correctly so they cannot slide under the pedals. Sound deadening material can reduce road noise and vibrations, but the effect depends on the material, how much you cover and how clean the surface is during installation. Mirrors, holders and trunk storage also belong here, and Covercraft is one of the brands in the category.

Frequently asked questions

What does the pedal ratio on a pedal assembly mean?

The ratio, for example 5:1 or 6.25:1, indicates how much the pedal multiplies your foot force against the master cylinder. A higher ratio typically gives more force but longer pedal travel. The right choice depends on the master cylinders and the brake system.

Can I fit a different seat or steering wheel in a road car?

It depends on the product and the car. Check the approval for the specific part number, and find out whether modifying the seat, bracket or steering wheel requires an inspection before the car is used on the road.

How do I make sure the floor mats fit?

Mats are typically made for specific model years, body styles and seat rows, for example the 1st or 2nd row or regular cab and supercab. Compare the product name with your car, and check whether the mat uses the car's retention points.

Does sound deadening make the car heavier?

Yes, sound deadening material adds weight, and how much depends on the material and the area you cover. In a lightweight track project, you can choose to cover selected areas such as the doors or floor rather than the entire cabin.
